AI-assisted intraoperative navigation for safe right liver mobilization in pure laparoscopic donor hepatectomy: an experimental multi-institutional validation study.

ABSTRACT: Minimally invasive liver surgery (MILS) offers significant benefits but faces limited adoption due to its steep learning curve. This study explores the potential of artificial intelligence (AI) in assisting the performance of major MILS by providing intraoperative navigation through real-time segmentation of the safe plane for dissection. We developed and validated a deep learning model for segmenting vascular structures and the avascular plane during pure laparoscopic donor right hepatectomy (PLDRH). The study utilized 48 PLDRH videos from three institutions, with 40 videos used for five-fold cross-validation and 8 for external validation. The U-Net architecture with Mix Transformer encoder was employed for segmentation. Model performance was assessed using Dice similarity coefficient (DS
